The cold start valve is also known as a ‘cold start injector’. It sits in your car’s intake manifold and links with the cold air intake. Your engine needs to be at the temperature to deliver power around the car. While older cars use a choke to deliver extra fuel, the cold start valve is its equivalent in modern cars. When your engine is too cold, your car’s computer commands the valve to inject more fuel into the system. This creates a richer air/fuel mix and allows the combustion process to occur. Symptoms of a failing cold start valve include failure to start your car and poor fuel efficiency. If your engine is flooding when you try to start your car, then the cold start valve could be leaking.
